11 Claims. c1. 74-531 My invention'relates primarily to improvements injalousie operators or the like although not limited thereto; and it is acontinuation in part of my copending application Serial Number 573,241,filed March 22, 1956 and now abandoned. Briefly and generally stated,the invention aims to provide a device as characterized which (1)eliminates the necessity for gearing; (2) is simple, durable andinexpensive in construction while being highly efficient in operation;and (3) which embodies positive means for effectively locking thelouvers or the like in adjusted position j. 1 L 1 Various other objectsand advantages of my advance in the art will be readily understood andappreciated by those versed in the art-upon'reference to the accompanying drawings which-illustrate two presently preferred examples of theinvention:- It is to be understood, how ever, that the disclosures areto be taken" illustrative, rather than limitative, since my inventiveconcept is sus ceptible of other-mechanical expressions within thespirit and scope of the" subject matter claimed hereinafter.

In the drawings, wherein the same reference characters have been used tothe designate the same parts wherever they appear throughout the severalviews- 1 'Fig. 1 is an inside elevation of a typical jalousie window,showing a device embodying the invention mounted at a conventionallocation on the jamb;

n p 2 bearing pin 7 between lever-carried bearing ears 3a.' The armextension of lever 3 has a pivotal connection as at with the lower endof an upwardly extending link member 9 whose upper end is pivoted as at12 to the usual louver control bar 11. Louver control bar 11 has j theconventional pivot connections 13 with the end flanges 14 of louvers 15.Thus, when the lever 3 is swung about pivot 4, 5 by handle 6 in the fullline position of the latter (Fig. 3), the louvers 15 are rocked inunison through the intervening linkage 9 and bar 11.

-Fig. 2 shows the lever 3 as having a disk-form major portion 3bextending through the window jamb structure and (see- Figs. 3 and 4)through a slot 1b in the base flange of bracket 1. As indicated inFigs-3 and 5, the supporting ears 3a for handle pivot pin or bearing 7are disposed adjacent the plane of the opposite side of bracket flangeportion 1a from the disk-form major portion 3b of lever 3. The drawingalso shows that the handlesuppo-rting ears 3a are carried by an edge ofthe disk portion 3b of lever 3 which is remote from the arm extensionwhich carries the link-connecting pivot 10.

' The means for clamping the louvers 15 in a set position will now bedescribed. In carrying out this phase of the invention, I provide arelatively stiff pressure plate 8 which is pivoted on the lever pivot 4,5 at the opposite side of the bracket flange portion 1a from the majorportion 312 of lever 3. The free end of pressure plate 8 extends betweenthe lever-carried ears 3a so that it will be thereby swung with lever 3and will always be in a position to be engaged by the cam end 6a ofhandle 6 when the latter is swung to the dotted line position of Fig. 3,which is the full line handle (6) position of Fig. 4. Engagement of cam6a with pressure plate 8 locks the louvers 15 in a set position by sofrictionally engaging pressure plate 8 with the bracket flange portionIt: as to lock the handle-carrying lever 3 against movement. The reasonfor the semi-circular outline of bracket Fig; 2 is a vertical section ofa typical jalousie, as

taken'on line 2-2 of Fig. l;

Fig. '3 is a top view of-the operator showing, in broken lines, thepositiono-f the handle when'its cam end-is clamping to prevent linkagemotion; and in full lines; the

Referring" to the drawings by reference characters 3 turning toFig's.PSI-inclusive, it will be seen'that' louvers 15 are operated mantrallythrough lever member 3 whicli is*piyotally j eonnected by pin 4'andbushing 5 to the semi-circular xtension la ofjthe outstanding flangeof an L br acket 1. The 'baseflange of L-bracke't 1 is an flange portion3b is so that there will always be a bracket flange portion adjacenthandle cam 6a and the underlying outer portion of pressure plate 8 to beengaged by thelatter. Pressure plate 8 constitutes a shiftable offsetextension of bracket flange portion 1a. Thus, flange portion 121 neednot be of such size as to marginally underlie cam 6a, and economy ofmetal is effected.

I Referring to the secon'd form of the invention illus trated in F igs.69, inclusive, numeral 20 indicates end carriers for the glass louvers21, which 'carriers are pivoted as at 22 to the window jamb structure 23asindicated. "The louver carriers 20 have rearwardly extending arms 20awhich are pivoted as at 24 to a vertically shiftable control bar 25corresponding to the control bar 11 of Fig. 2.

Actuation of the control bar 25 is efiected by the link 27 which ispivoted to the control bar as indicated at 26 adjacent one end. Theother end of link 27 is pivoted as at 28 to the lever extension 29 ofthe disk 30 which projects through the window jamb structure and throughthe slot 31 in the base flange 32a of the L-bracket 32' whichis-generally similar to the bracket 1 of Figs. 1-5, inclusive. r

The bracket 32 is secured as at 33 to the jamb structure 23 andsaidL-bracket 32 has the outwardlyex tending flange 34 providing thearginally curved medial extension 34a "to which the disk 30 is. pivotedas indicated at 35. The lever-carrying disk 30 has, at is opposite edgefrom the lever 29, the extension 30a which chored to the jamb'structureat the window openingby I bolts 2, 2, and-the lever'3 is' fitte'd at oneendwith a pivotally connected operating handle 6.':..The'lever-bpertaing handle'6 provides'a camf6a at its inner. endandisipiv'oted inwardly thereof on'the extends rearwardly of the rear edgeof the flange extension 34a of bracket flange 34. The disk extension 30acarries the spacedly opposed and laterally extending ears 36 whichextend across the plane of flange extension 34a and pivotally support,as at 37, the inner end of the handle 38 at the opposite side of flangeportion 34g 3 from disk 36. The handle 38 is preferably of plasticfriction-like material and its cam-providing inner end 38a isadapted toswing as in Figs. 7 and 8 to lockingly engage the adjacent surface offlange portion 34a.

Thus, the handle 38 as shown, has a dual funtioninthat it functions as alocking member and alsov as an operating handle for the disk 30,, 29 asindicated in Fig. 6. It will be understood, as above indicated,thatafter the louvers have been appropriately adjusted. by manipulationof the handle 38 in the Fig. 6 position, it is swung about its pivot 37as indicated in Figs. 7 and. 8-, so that the cam action inner end 38awill bear against the adjacent face of the bracket flange portion 34asoas to lock the lever 29 and disk 30 against. movement.

A modified form of the handle 38 is shown at 40 in Fig. 9 and providescross-sectionally U-shaped major portion 41 into the outer end of whichis fitted the friction block 42 which is held in place by a pivotpinsuch. as 37 (Fig. 8) and can be renewed when necessary so as to avoidreplacing the entire handle due to wear at the cam action end thereof.
